- Brown color lens tends to absorb short wavelength of light. This is good for any kinds of outdoor activity.
- Gray lens usually absorb wide range of wavelength, so it is good when you are going to be exposed to strong sunlight.
- Green lens does not distort object’s natural color.
- Yellow lens is ideal for driving in a cloudy day.
